A moving picture coding apparatus includes an intra-inter prediction unit which calculates a second motion vector by performing a scaling process on a first motion vector of a temporally neighboring corresponding block, when selectively adding, to a list, a motion vector of each of one or more corresponding blocks each of which is either a block included in a current picture to be coded and spatially neighboring a current block to be coded or a block included in a picture other than the current picture and temporally neighboring the current block, determines whether the second motion vector has a magnitude that is within a predetermined magnitude or not within the predetermined magnitude, and adds the second motion vector to the list when the intra-inter prediction unit determines that the second motion vector has a magnitude that is within the predetermined magnitude range.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the collocated block is included in a picture adjacent to the current picture in a sequence of pictures.
3. The method of claim 1, wherein the collocated block is included in a picture other than a picture adjacent to the current picture in a sequence of pictures.
4. The method of claim 1, wherein the neighboring block spatially adjacent to the current block is located above the current block.
5. The method of claim 1, wherein the neighboring block spatially adjacent to the current block is located left of the current block.
6. The method of claim 1, wherein the motion vector predictor is associated with a difference motion vector.
8. The apparatus of claim 7, wherein the collocated block is included in a picture adjacent to the current picture in a sequence of pictures.
9. The apparatus of claim 7, wherein the collocated block is included in a picture other than a picture adjacent to the current picture in a sequence of pictures.
10. The apparatus of claim 7, wherein the neighboring block spatially adjacent to the current block is located above the current block.
11. The apparatus of claim 7, wherein the neighboring block spatially adjacent to the current block is located left of the current block.
12. The apparatus of claim 7, wherein the motion vector predictor is associated with a difference motion vector.
